Human safety against touch voltage hazards is the most important factor in electric power systems. Danger of touch voltage can occur if humans touch the live parts directly or indirectly. Indirect touch can occur when humans touch the open conductive parts (BKT) of equipment which under normal circumstances has no voltage but can be live due to leakage current due to damage to insulation in electrical cables. Therefore it is necessary to protect against indirect touch voltage. This study aims to analyze indirect touch voltage protection using Earth Leakage Circuit Breaker (ELCB) and Miniature Circuit Breaker (MCB). In this study, 30 mA ELCB and 2 A MCB were used as protection against indirect touch voltage hazards. The research data were obtained by using the experimental method, namely by conducting experiments in the laboratory. From the experimental results in the laboratory, it was found that the 30 mA ELCB is more sensitive as protection against indirect touch voltage than the MCB. This is because the working principle of the ELCB is based on the leakage current that occurs in the BKT, while the working principle of the MCB is based on the total current (leakage current and load current) flowing through the MCB.

Graphene is a new type of material that has excellent electrical, thermal, magnetic, optical, mechanical and chemical properties. The graphene synthesis method that is currently being developed is through electrochemical peeling technique because it has the advantages of a fast manufacturing process, environmentally friendly, and low cost in the production process, as well as low value of the resulting material defects. This study aims to determine the effect of different anodes in the synthesis of graphene using the electrochemical stripping method of the graphite electrode layer. The anodes that were varied in this study were a commercial graphite electrode and an artificial graphite electrode in the form of a graphite-Phenol Formaldehyde (graphite-PF) composite. The cathode in this study is a fixed variable using commercial graphite. The result of this research is that the Graphite-PF composite electrode can act as an anode in the graphene synthesis process by electrochemically stripping the graphite electrode layer, although the resulting graphene is lower than the use of commercial graphite electrodes as anode. The 5A current from the power supply connected to the graphite electrode shows the best results. The use of a solenoid modified reactor can increase the weight of the graphene formed.

Fuse dan recloser secara tradisional digunakan untuk mereduksi gangguan pada saluran udara dimana pada feeder utama dipasang recloser dan pada lateral feeder dipasang fuse. Fuse adalah alat proteksi murah dan andal yang akan melebur dalam beberapa siklus akibat suatu arus gangguan yang tinggi. Untuk minimalisasi jumlah fuse yang putus, dilakukan back-up oleh recloser . Pada gangguan temporer, recloser akan mengkliring gangguan yang menjadi prioritas fuse . Skema proteksi ini dikenal sebagai fuse saving operation . Mekanisme koordinasi proteksi ini akan berubah ketika dilakukan integrasi Abstract Fuse and recloser are traditionally used to reduce interference in the airways where the main feeder is installed recloser and the lateral feeder is installed fuse. Fuses are inexpensive and reliable protection devices that will fuse over several cycles due to a high fault current. To minimize the number of broken fuses, a back-up is performed by the recloser. In the case of temporary disturbances, the recloser will clear the disturbance that is the priority of the fuse. This protection scheme is known as fuse saving operation. This protection coordination mechanism will change when the generating unit is integrated into the network. This occurs due to changes in the fault current due to the contribution of the fault current from the generator. The magnitude of the significant change is influenced by the location and capacity of the generating unit. The research objective is to develop an evaluation tool for the fuse mitigation process that is affected by mal coordination due to the location of the generator and the penetration level of the generator. The research methodology was carried out by developing software using MATLAB with the subject of the 34 node IEEE Test network study. The results showed that a low penetration level of 20% only had a small impact on protection coordination and a high penetration level only prevented mal coordination in installations near substations.

In football matches, possession of the ball becomes an assessment and evaluation material that shows opportunities to score. Calculation of ball possession is done by calculating the time of the total game time manually. Even though it is only an outline of the assessment of football matches, there are still many errors in writing match statistics due to human error, especially in Indonesia. To overcome this problem, in this study an application was made to collect ball possession statistical data using background subtraction. Several frames on the recording of a football match are taken to make a reference background and then a subtraction process is carried out with the frame during the match. The result of the subtraction will then form a rectangular border whose sides indicate the outermost object detected. The rectangular position will be divided into five conditions that determine ball possession statistics. The detection results are compared with human judgments to assess the detection accuracy. The result of this research is a prototype in the form of an application as the application of the background subtraction method. Based on the results of the research that has been done, the detection accuracy is 91%. Most of the errors occur because the object is idle for too long which makes the object in the background and is not detected by the system.

Currently, human awareness to dispose of waste is not in accordance with the type of waste in its place, so all types of waste are mixed. The mixing of various types of waste can damage or reduce the value of materials that can be reused, especially metal-based waste which has a high selling value. By sorting the waste according to the type of waste, the recycling process can be carried out. Therefore, in this paper an innovation is made for a trash can that can separate metal and non-metallic types of waste automatically. The way this system works is that it is placed in an initial shelter, then detected by a proximity sensor to determine whether the waste is metal or non-metallic. When garbage is detected, the garbage bin can drop the garbage into the metal bin with the help of a servo. Likewise with non-metallic waste. The volume of waste can be detected by ultrasonic sensors. If the volume of the trash can is at its maximum, the alarm can sound. Furthermore, the data on the volume of the trash can is transmitted by the wifi module to the application on the smartphone, so that the garbage officer can find out if the volume of waste reaches the maximum. After testing, the e-Separator system can be categorized as very good with an accuracy of sensor readings that are above 95% accuracy of distance accuracy in detecting volume which reaches more than 98%. The average delay of servo movement is faster than 5 seconds and the error percentage in sending data to applications reaches 0%.

Motor vehicle security systems using conventional ignition are considered vulnerable to be hacked. So replacing the ignition key of a motorized vehicle using Radio Frequency Identification (RFID) technology from the Electronic Identity Card (E-KTP) and vehicle tracking are alternatives for vehicle security. In this study, an E-Lock system has been realized which can be a solution to limit access to the use of motorized vehicles by unauthorized persons. The tool is made using an RC522 RFID module to read the E-KTP ID of motorized vehicle owners in order to activate the ignition. The ATMega2560 microcontroller will activate the relay as a parameter ON/OFF switch on the motorized vehicle power supply line. The system is also equipped with Global Positioning System (GPS) tracking which can be accessed via mobile and web applications. Mobile application users can send complaint reports as well as the latest location data from their motorized vehicles to the web. Complaint information on the web can be accessed by the police for tracking. The test was carried out 10 times for 5 samples of E-KTP. The E-Lock tool shows good performance in reading the E-KTP ID and activating the relay with an effective reading distance of 2.5 cm. The system can send data when the signal is stable, and the application can access the data according to the database. In the GPS test, the error value is less than 1% with the smallest error distance of less than 1 meter and the farthest error distance of more than 5 meters.
